Problems solved by technology

[0003] In the emission sources of residential buildings and commercial buildings with catering functions, the oily fume is directly discharged through the range hood without treatment, or concentratedly discharged to the outdoor environment through the roof flue. Any treatment will cause serious pollution to the atmosphere. Studies have shown that the instantaneous PM2.5 emission concentration during the three meals of family meals is as high as 200ug / m 3
[0004] Based on this, it is urgent to develop a high-efficiency treatment method for cooking fume from the roof of the building. The existing methods for the treatment of soot particles mainly include: mechanical removal method, electrostatic method, washing method, adsorption method, catalytic combustion method And the combination of these methods, but these methods have certain defects, such as high energy consumption, large consumption of auxiliary substances, etc., and cannot be applied to the treatment of oil fume emission on the roof
